Dust ion counter in mask industry Dust ion counter in mask industry

The 2.83L dust particle counter is a specialized measuring instrument used to detect the concentration, size, and cleanliness level of dust particles in clean rooms, cleanrooms, dust-free workshops, and air. The large screen LCD display dust particle counter has unique characteristics and is currently an advanced product among similar products in China. The 2.83L dust particle counter adopts imported semiconductor laser tubes and imported semiconductor photosensitive receiving tubes.

It is an instrument used to measure the number and particle size distribution of dust particles per unit volume in clean environments. The basic principle is that the detection laser of the optical sensor is scattered by dust particles and received by a photosensitive element to generate a pulse signal. The pulse signal is output and amplified, and then subjected to digital signal processing. By comparing it with the standard particle signal, the comparison result is represented by different parameters. The measurement parameter settings, measurement result display, buttons, timing, printing, time, date, data storage, etc. of the instrument are all controlled and implemented by a built-in microcontroller (MCU). The instrument can simultaneously display the temperature and humidity of the environment and monitor and report the working status of the laser particle sensor.

One sampling can simultaneously measure the number of dust particles in six particle size channels, and observe the number and changes of particles in six particle size channels, which can meet the needs of the pharmaceutical industry (pharmaceutical factories, drug testing institutes, hospital operating rooms, etc.); The electronics industry (semiconductor factories, production and processing of precision machinery, etc.); Food hygiene industry (precision processing of dairy products, sealed meat products, seasoning foods, agricultural products, etc.); Manufacturers of filters, inspecting the quality and efficiency of filters, etc; The inspection of clean rooms (areas) required for precision machining and precision testing in the fields of optics, aerospace, etc.
